Template for doorlocks



y 1933. E. H. JOHNSON 9 5 OOOOOOOOOOOOOOOOOO KS jn bmlr Pate'tecl May 2, 1933 y UNITED) STATES" i ELVIN EJoHvsoNmF wmsm'rka, ILLIN'QIS e x i TEMPLATE FonDooR ocxs My invention relates to builders' hardware i and includes among'its objects and advantages improved convenience and facility in` the correct installation of secret door latches. A'secret door latch comprises oooperating means carried by `a fixed member, such as a, box or cabnet, and a movable member, such e popular.

In the assembly of such a device, after one necessary to fasten the other portion on-the movable member n postonto regster accurately with the previously inounted portion when the movable member is fastened. Often the inside surface of the movable mem- :ber is only accessible when the member is open, and it becomes a diflicult and, except to an experienced cabinet maker, an almost impossible task to find the correct position' for fastenin'g the other portion ofthe device. In the accompanying drawing, Fig. 1 is e a side elevation of the parts carried by the door and cabinet when the door `is in closed s Fig. 4 isa View, as on horizontal line 4-4 of Fig. 3, indicating'the use of the template.

In'the selectedembodiment of apparatus according to the invention,-there is provided a template 10 by means of which the housing 12 and the hook 14 can both be located with ,convenience and accuracy.

` In proceeding according to the invention, I first 'locate' the housing 12-in place on the stop strip 16.` In doing this, the only dimension that need be at all accurately measured i Without further elaboration, the foregoa is the distance'from the front of the housing to the front edge of the stop strip The tem plate 10 is placed with one Vertical` edge flush with the edge of the stop strip and the means of this sort havevb ecome inoreasingly,

a horizontal section through a, box or cabinet equipped with a secret door latch; i Fig. 2 is` housing and a template applied thereto, and

holes in the template indicate the positions forthe screws to mount the housing 12, which is held in'pla'ce by three Wood screws ,18, 20 and 22. 'The template is now laid' over the housing, and' the template and housing'are mounted together as indicated 'in Figs. 3 and& In this position the prongs 24 ofthetemplate` are correctly positioned to indicatethe positions for the screws for mounting the hook 14; r I e The movable element 26 may now be closedlightly against the template to' form marks-'or indentations on its surface asa gude forimounting the hOOk'ld. If the" inner surface of the door happensto be too rough for ready identification of the nden tations formed by' the prongs 24, it may readly be smoothed with sandpaper or a plane, or a bit of paper may be pasted' over t to ,receve the impressions of the prongs.

After the impressi'ons are formed,`-it is a 'simple matterto open the door and 'put in the fastening screws 28 at-the points j indicated-by the indentations. The templateis removed and discarded and'the assembly is complete. 1; i

-` Ihave illustrated a keyhole slot at 30 for,

the lower central screw 20, andopen-ended slots 32 for the upper screws 18 and 22 so thatthe template can be removed by merely loosenng the screws without removing them.

While the latching mechanism in the a housing 12 is oapable of functioning either end up,'- I prefer to mount it with the screw 20 low`ermost. in all instances. If the door 4 26, were hinged at the other side, the housng 12 would need to be located in the corpurpose ininstalling the device in any desired position.

ingwill so fully explain my invention that others may, by applying knowledge current at the time of application, readily adapt the same for use under various conditions of service.

I claim:

1. A template for use in installing a latohing device, conprising a body provided with openings to locate the 'fastening means for one portion of a latching devce, the body being adapted to be superposed on said porton and to be Secured thereto by the same fastening means entering said openings, said body having means projecting from one of its edges for locating the fastening means for the other portion of the latching devce.

2. A template for use in installing a latohing device, comprising a body provided With openings to locate the fastening means for one portion of a latching device, the body being adapted to be superposed on said por ton and to be Secured thereto by the same fastening means enterng said openings, said body having points projecting from one of its edges for locating the fastening means for the other portion of the latching device, said points being duplioated symmetrically on the opposite edge of? the body.

3. A template for use in installing a latching deviee, eomprising a body having slots therethrough arranged to locate fastening screws for one portion of a latching device 311` and an edge arranged to register With ar predetermined line for spacing said Slots a predetermined distance from said line, said body being shaped to be thereafter superposed on said portion and Secured thereto by the same fastening screwsentering said slots, said body having a pointed edge for locating the fastening means for the other portion of. the latehing devce When said body is superposed on said first portion.
